porose, rather thin-walled ; pedicel pale yellow, more slen- 

 der, sharply twisted ; capsule pale, tawny, deeply sulcate 

 when old, and provided with more distinct longitudinal bands 

 of orange-colored, elongated, sinuous and thick-walled cells. 



Miquelon Island (Dr. Delaware). 



By the pale tint of the tufts, pedicels and capsules, this 

 remarkable variety, with rather the appearance of D. longi- 

 folium, belongs to the group of forms generally designated 

 as D. pallidum C. MiilL, or Z). scoparium var. -pallidum, but 

 it is distinct by its narrower leaves, with a longer and more 

 sharply serrate subula and its deeply sulcate capsule. 



Dicranum Howellii. — In soft, rather silky, yellowish 

 green tufts. Stems slender, erect, simple or dichotomous, to- 

 mentose below, 4-12 cm. long. Leaves not crowded, secund 

 or erecto-patent, narrowly lanceolate, long subulate, nearly 

 setaceous, serrate in the upper half, often slightly undulate 

 when dry, 6-10 mm. long, -75-1 mm. broad at base; costa 

 more or less serrate at back toward apex ; cell-walls porose, 

 but scarcely thickened. Inner perichretial bracts sheathing, 

 rather suddenly narrowed into a long flexuous point, entire 

 or coarsely sinuate at base of the subula. Pedicel pale, at 

 last sharply twisted to the left, 25-35 mm. long ; capsule ru- 

 fescent, cylindraceous, arcuate, slightly plicate when old ; 

 lid with a long curved beak. Inflorescence monoecious or 

 pseudo-monoecious ; male flowers sessile, axillary, or set upon 

 small, slender flexuous branchlets. 



Oregon ( Th. Howell, Z. F. Henderson). 



This plant is a remarkable form, belonging to the group 

 of D. scoparium, of which it may be only a sub-species, but 

 well characterized by the form of its perich^tial bracts, nar- 

 rowed at apex, and not abruptly subulate from the rounded 

 apex, as is the case in D. scoparium. In habit and shape of 

 the leaves it specially resembles the last variety. 



Dicranum Miqueloxense. (Florule de Tile Miquelon, 

 42.)— In small, compact, yellowish green tufts. Stems dicho- 

 tomous, radiculose below, 1-3 cm. long. Leaves small, short, 

 erect-imbricate or slightly incurved, oblong-lanceolate, acute 

 or obtuse, concave, entire or minutely sinuate-denticulate at 

 apex, 2-3 mm. long, .50-. 75 mm. broad; costa vanishing 

 near the apex, smooth or scarcely rugose at back. Cells of 

 the areolation smooth, small, shoVt, quadrate or irregularly 

 angular in the upper half, rectangular, 1-3 times longer than
